with respect to scoring and possessions. The shot clock definitely helped the game at that level. I can probably see a time where the shorten a little bit more to say 60 and 45 or something like that but I think the 80/60 rule is perfect.

As I said before, the shot clock is likely coming to HS and then, eventually high level youth lacrosse leagues/tournaments. Too many games at that level are dragging like they did in college pre-shot clock. this is especially true in the more talented games. Looking at you coach this weekend that was up 9 to 2 with 4 minutes (and won all but one faceoff in the game), calling time out and essentially stalled the last 5 minutes of the game. My son in 6th grade played in a tournament last fall that applied the NCAA shot clock rule and it was fine. There were no more procedure calls in that tournament then a tournament that had a 20 second, 10 second get it in the box rule applied. In fact, it was probably less of an issue.

Big issue with the shot clock is the cost of getting the clocks. Certainly doable for HS (and Howard County, MD's club league is going to a shot clock for the 7th and 8th grade elite divisions next spring) but likely harder for your random youth tournament in the middle of a cow pasture in the middle of no where PA that would need 10 or so for it to work (plus the labor costs of running it).

Duke illustrated the two instances where review should be added:
1) Crease violations on scored goals (especially OT)

2) Hits to the head - Duke player would have gotten 3 minutes and ejection if that hit on CKav was reviewed. CKav got a burst eardrum and surprised not a concussion

Even from the Club Seats, everyone in the section was shouting "crease!" (the action was coming towards us).

That rule has to be amended: easiest way for tourney is replay.
